Power Mirror Function Test
POWER MIRROR / FUNCTION TEST
NOTE: To test, remove the driver's door panel, then disconnect all of the connectors from the door panel.
NOTE: Check the No. 17 (7.5 A) fuse in the under-dash fuse/relay box before testing.
One or Both Inoperative:
1. Check for voltage between the BLK/YEL terminal and body ground with the ignition switch ON (II). There should be battery voltage.
If there is no voltage, check for:
- Blown No. 17 (7.5 A) fuse in the under-dash fuse/relay box
- An open in the BLK/YEL wire
If there is battery voltage, go to step 2.
2. Check for continuity between the BLK terminal and body ground.
There should be continuity; check for:
- An open in the BLK wire
- Poor ground (G501, G502)
Left Mirror Inoperative:
Connect the BLK/YEL terminal of the 10-P connector to the YEL/RED1 terminal and the YEL/WHT (or YEL/BLK1) terminal to body ground with jumper wires.
The left mirror should tilt down (or swing left) when you turn the ignition switch ON (II).
If the mirror does not tilt down (or does not swing left), check for an open in the YEL/WHT (or YEL/BLK1) wire between the left mirror and the switch. If the wire is OK, check the left mirror actuator.
If the mirror neither tilts down nor swings left, repair the YEL/RED1 wire between the left mirror and the switch.
If the mirror operates properly, check the mirror switch.
Right Mirror Inoperative:
Connect the BLK/YEL terminal of the 10-P connector to the BLU/WHT terminal and the YEL/WHT (or BLU/BLK) terminal to body ground with jumper wires.
The right mirror should tilt down (or swing left) when you turn the ignition switch ON (II).
If the mirror does not tilt down (or does not swing left), remove the right door panel and check for an open in the YEL/WHT (or BLU/BLK) wire between the right mirror and the switch. If the wire is OK, check the right mirror actuator.
If the mirror neither tilts down nor swings left, repair the BLU/WHT wire between the right mirror and the switch.
If the mirror operates properly, check the mirror switch.
